Abstract: PROBLEM TO BE SOLVED: To increase a blowing rate of a blowing fan which feeds cooling air to a shaft-sealing device of a variable capacity compressor. SOLUTION: A variable capacity compressor has a housing 3 in which a rotary shaft 11 that is mechanically connected to a pulley 1 and rotated and a variable capacity compression mechanism 13 are housed, and a shaft sealing device 14 which prevents leakage of fluid from the periphery of the rotary shaft 11. In such a compressor, a blowing fan 15 is integrally and rotatably arranged on the pulley l so as to oppose an outer wall surface of the housing 3. Cooling air is fed at leat to the periphery of the shaft sealing device 14 by means of the blowing fan 15. An elastic piece is fitted to the blowing fan 15, which piece can be elastically deformed and easily cut by mechanical contact. The elastic piece 16 is elastically abutted against the outer wall surface of the housing 3 immediately after arranging onto the blowing fan 15 to eliminate a gap between the blowing fan 15 and the housing 3.

Abstract: PROBLEM TO BE SOLVED: To provide a flexible coupling which can absorb misalignment while ensuring durability of a compressor and preventing malfunction of a torque limiter mechanism. SOLUTION: A driven rotor 220 is supported rotatably by a front housing 101 (cylindrical part 102) of the compressor 100. Thereby, most of the eccentricity power due to rotation of a coupling 200 can be accepted by the front housing 101 having higher rigidity than shafts 101, 310, and a bending moment acting on the shafts 101, 310 and a load working on a bearing (a radial rolling bearing 320 and a bearing which supports the shaft 101 arranged in the compressor 101 rotatably) can be reduced, then reliability and durability of the compressor 100 can be secured, even under low speed rotation and also under high speed rotation. Further, since most of the eccentricity power caused by the rotation of the coupling 200 is received by the front housing 101, the eccentricity power can be prevented from being acted on a limiter 230 and the malfunction of the limiter 230 can be prevented.

Abstract: PROBLEM TO BE SOLVED: To prevent cracking, wear, and deformation of a damper by force acting on a contact face of the damper when transmitting torque.
SOLUTION: The direction in which mechanical strength of a protection membrane 10 becomes the maximum is substantially 45 degrees for the direction of force acting on the protection membrane 10 in accordance with torque transmission to prevent that the direction in which mechanical strength of the protection membrane 10 is low agrees with the direction of force acting on the protection membrane 10 in accordance with torque transmission. It is possible to prevent direct contact of the contact face 9b of the damper 9 with an outer plate 8 due to the occurrence of crack in the protection membrane 10 to prevent wear and deformation of the damper 9 due to the occurrence of crack in the damper 9 and prevent erroneous operation of torque limiter function.

Abstract: PROBLEM TO BE SOLVED: To make strength of parts other than a bridge section, which form fracture parts, higher than that of the bridge section while preventing enlargement of a coupling (hub). SOLUTION: The bridge sections 15 are located on the line connecting projections 13 to the rotation center o.Maximum stresses occurring in respective projections 13 in transmitting torque are substantially the same in all of the plurality of projections 13.Therefore, the maximum stresses occurring in the projections 13 decrease for the same transmitted torque comparing with a case where stress concentrates on a specific projection 13, so that the strength of the parts other than the bridge section 15 can be increased without causing enlargement of the hub 11.As a result, while preventing enlargement of the whole hub 11, a mis-operation such as breakage of the bridge sections 15 before exceeding a predetermined torque can be prevented.

Abstract: PROBLEM TO BE SOLVED: To constitute a over load torque limitter mechanism having a torque fluctuation absorbing function in the power transmission of a compressor for air conditioning of a vehicle. SOLUTION: When a compressor 4 is operated in a normal condition, turning effort from an engine is transmitted to the rotary shaft 6 of the compressor 4 through a pulley 1, a rotor 2, a second holding member 13, a rubber made elastic member 15, a first holding member 12, and hubs 10, 7, and thereby, the compressor 4 is operated. At the time of normal operation, torque fluctuation is absorbed by the elastic member 15. At the time of overload such as locking of the compressor 4, the elastic member 15 is deformed, the outer peripheral surface of the elastic member 15 is slid on the inner circumferential surface of the first holding member 12 so as to stop transmission of power. A recessed part having a space facilitating deformation on a part where sliding is generated by deformation at the time of over load is formed on the elastic member 15.

Abstract: PROBLEM TO BE SOLVED: To change a position of a pulley rotary shaft direction without changing design of a torque limiter mechanism transmitted with torque from a drive side rotary member and a driven side rotary member, in a torque transmitting device having a torque limiter function. SOLUTION: A drive side rotary member is constituted by a pulley 1 and a rotor 2 formed in a separate unit from this pulley 1, the rotor 2 is provided with a connection surface 2a extended in a radial direction of the rotor 2, and a second hole member 13 is connected to this connection surface 2a. In this way, by connecting the second hold member 13 to the connection surface 2a of the rotor 2 formed in a separate unit from the pulley 1, in the case that a position of the pulley 1 is to be moved in its rotary shaft direction by a change of specifications, the position of the pulley 1 connected to the rotor 2 is required to be only displaced in a rotary shaft direction.

Abstract: PROBLEM TO BE SOLVED: To interrupt transmission of torque at a predetermined torque even when the temperature of an elastic member drops. SOLUTION: Coefficient of linear expansion of an inner plate 113 is made larger than that of an outer plate 122. When temperatures of both plates 113 and 122 and an elastic member 130 drops, even though a transmission torque increases due to the temperature drop of the elastic member 130, a meshing quantity δ1 during torque transmission decreases because gap δ2 between the elastic member 130 and the outer plate 122 becomes larger. Consequently, the increase rate of torque transmission in regard to the temperature drop of the elastic member 130 is smaller compared to when materials (coefficient of linear expansion) of both plates 113 and 122 are the same. Thus, transmission of torque is interrupted at a predetermined torque even when the temperature of the elastic member 130 drops.
